71980093 ÷ 310 
We want to divide 71980093 by 310.

Moving on to step 1:
7 divided by 310 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 310

Step 2:
The number 310 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 310

Advancing to step 3:
310 can be fit into 719 2 times, resulting in a remainder of 99.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 620 from 719 to get 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 310

Advancing to step 4:
The number 310 fits into 998 3 times, leaving a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 930 from 998, we get 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 310

Going ahead to step 5:
When dividing 680 by 310, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Deduct 620 from 680 and we're left with 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 310

Advancing to step 6:
The number 310 fits into 600 1 times, leaving a remainder of 290.
Put 1 as the next digit of the answer. 
Result so far: 2321.0
If we subtract 310 from 600, we get 290.
Include the next digit (9) from the dividend after 290, then repeat: 2909 / 310

Going ahead to step 7:
310 goes into 2909 9 times with a remainder of 119.
The number 9 becomes the next digit in our result. 
Result so far: 23219.0
Deduct 2790 from 2909 and we're left with 119.
Append the next digit (3) from the dividend to 119 and continue with: 1193 / 310

Moving on to step 8:
310 can be fit into 1193 3 times, resulting in a remainder of 263.
The next digit of our result is 3. 
Result so far: 232193.0
Deduct 930 from 1193 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
2630 divided by 310 is 8 with a remainder of 150.
The next digit of our result is 8. 
Result so far: 232193.8
If we subtract 2480 from 2630, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
310 can be fit into 1500 4 times, resulting in a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 232193.84
The remainder is 260 after subtracting 1240 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
2600 divided by 310 is 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 232193.848
If we subtract 2480 from 2600, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
1200 divided by 310 is 3 with a remainder of 270.
Write down 3 as next digit of the result. 
Result so far: 232193.8483
If we take 930 away from 1200, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 13:
The number 310 fits into 2700 8 times, leaving a remainder of 220.
Write down 8 as next digit of the result. 
Result so far: 232193.84838
Subtracting 2480 from 2700 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
310 goes into 2200 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 232193.848387
Deduct 2170 from 2200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
When dividing 300 by 310, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 232193.848387
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 16:
When dividing 3000 by 310, we get 9 with a remainder of 210.
The next digit of our result is 9. 
Result so far: 232193.84838709
Deduct 2790 from 3000 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 232193.84838709, with a leftover of 2.1e-07.
